Abstract

This invention provides plasticizer additive compositions, for use in cementiferous compositions, which enhance the early gain of compressive strength. The plasticizer additive compositions comprise an aqueous solution of a copolymer or salt thereof, comprising an ethylenically unsaturated monomer having a hydroxyl functional group and an accelerator additive.
